Supersymmetric partition functions and the three-dimensional A-twist / Closset, Cyril (CERN) ; Kim, Heeyeon (Perimeter Inst. Theor. Phys.) ; Willett, Brian (Santa Barbara, KITP)
We study three-dimensional $\mathcal{N}=2$ supersymmetric gauge theories on $\mathcal{M}_{g,p}$, an oriented circle bundle of degree $p$ over a closed Riemann surface, $\Sigma_g$. We compute the $\mathcal{M}_{g,p}$ supersymmetric partition function and correlation functions of supersymmetric loop operators. [...]

$\mathcal{N}{=}1$ supersymmetric indices and the four-dimensional A-model / Closset, Cyril (CERN) ; Kim, Heeyeon (Perimeter Inst. Theor. Phys.) ; Willett, Brian (Santa Barbara, KITP)
We compute the supersymmetric partition function of $\mathcal{N}{=}1$ supersymmetric gauge theories with an $R$-symmetry on $\mathcal{M}_4 \cong \mathcal{M}_{g,p}\times S^1$, a principal elliptic fiber bundle of degree $p$ over a genus-$g$ Riemann surface, $\Sigma_g$. Equivalently, we compute the generalized supersymmetric index $I_{\mathcal{M}_{g,p}}$, with the supersymmetric three-manifold ${\mathcal{M}_{g,p}}$ as the spatial slice. [...]

Seifert fibering operators in 3d $\mathcal{N}=2$ theories / Closset, Cyril (CERN) ; Kim, Heeyeon (Oxford U., Inst. Math.) ; Willett, Brian (Santa Barbara, KITP)
We study 3d $\mathcal{N}=2$ supersymmetric gauge theories on closed oriented Seifert manifold---circle bundles over an orbifold Riemann surface---, with a gauge group G given by a product of simply-connected and/or unitary Lie groups. Our main result is an exact formula for the supersymmetric partition function on any Seifert manifold, generalizing previous results on lens spaces. [...]

A-twisted correlators and Hori dualities / Closset, Cyril (CERN) ; Mekareeya, Noppadol (Milan Bicocca U. ; INFN, Milan Bicocca) ; Park, Daniel S. (Rutgers U., Piscataway)
The Hori-Tong and Hori dualities are infrared dualities between two-dimensional gauge theories with $\mathcal{N}{=}(2,2)$ supersymmetry, which are reminiscent of four-dimensional Seiberg dualities. We provide additional evidence for those dualities with $U(N_c)$, $USp(2N_c)$, $SO(N)$ and $O(N)$ gauge groups, by matching correlation functions of Coulomb branch operators on a Riemann surface $\Sigma_g$, in the presence of the topological $A$-twist. [...]

Large $N$ topologically twisted index: necklace quivers, dualities, and Sasaki-Einstein spaces / Hosseini, Seyed Morteza (Milan Bicocca U. ; INFN, Milan Bicocca) ; Mekareeya, Noppadol (CERN)
In this paper, we calculate the topological free energy for a number of ${\mathcal N} \geq 2$ Yang-Mills-Chern-Simons-matter theories at large $N$ and fixed Chern-Simons levels. The topological free energy is defined as the logarithm of the partition function of the theory on $S^2 \times S^1$ with a topological A-twist along $S^2$ and can be reduced to a matrix integral by exploiting the localization technique. [...]

On exact correlation functions in SU(N) $ \mathcal{N}=2 $ superconformal QCD / Baggio, Marco (Zurich, ETH) ; Niarchos, Vasilis (Crete U.) ; Papadodimas, Kyriakos (CERN ; U. Groningen, VSI)
We consider the exact coupling constant dependence of extremal correlation functions of ${\cal N} = 2$ chiral primary operators in 4d ${\cal N} = 2$ superconformal gauge theories with gauge group SU(N) and N_f=2N massless fundamental hypermultiplets. The 2- and 3-point functions, viewed as functions of the exactly marginal coupling constant and theta angle, obey the tt* equations. [...]

Bootstrapping the Three-Dimensional Supersymmetric Ising Model / Bobev, Nikolay (Leuven U.) ; El-Showk, Sheer (CERN) ; Mazac, Dalimil (Perimeter Inst. Theor. Phys.) ; Paulos, Miguel F. (CERN)
We implement the conformal bootstrap program for three-dimensional CFTs with $\mathcal{N}=2$ supersymmetry and find universal constraints on the spectrum of operator dimensions in these theories. By studying the bounds on the dimension of the first scalar appearing in the OPE of a chiral and an anti-chiral primary, we find a kink at the expected location of the critical three-dimensional $\mathcal{N}=2$ Wess-Zumino model, which can be thought of as a supersymmetric analog of the critical Ising model. [...]

Laplacian spectrum on a nilmanifold, truncations and effective theories / Andriot, David (CERN) ; Tsimpis, Dimitrios (Lyon, IPN)
Motivated by low energy effective theories arising from compactification on curved manifolds, we determine the complete spectrum of the Laplacian operator on the three-dimensional Heisenberg nilmanifold. We first use the result to construct a finite set of forms leading to an N=2 gauged supergravity, upon reduction on manifolds with SU(3) structure. [...]

Wall-crossing made smooth / Pioline, Boris (CERN ; Paris U., IV ; Paris, LPTHE)
In $D=4,N=2$ theories on $R^{3,1}$, the index receives contributions not only from single-particle BPS states, counted by the BPS indices, but also from multi-particle states made of BPS constituents. In a recent work [arXiv:1406.2360], a general formula expressing the index in terms of the BPS indices was proposed, which is smooth across walls of marginal stability and reproduces the expected single-particle contributions. [...]

A string realisation of $\varOmega$-deformed Abelian $\mathcal{N}=2^*$ theory / Angelantonj, Carlo (INFN, Turin ; Turin U.) ; Antoniadis, Ignatios (Paris, LPTHE ; UPMC, Paris (main) ; U. Bern, AEC) ; Samsonyan, Marine (CERN)
The $\mathscr{N}=2^*$ supersymmetric gauge theory is a massive deformation of $\mathscr{N}=4$, in which the adjoint hypermultiplet gets a mass. We present a D-brane realisation of the (non-)Abelian $\mathscr{N}=2^*$ theory, and compute suitable topological amplitudes, which are expressed as a double series expansion. [...]
